Description

Technical Field

[0001] The utility model belongs to the technical field of projectors, and in particular relates to a smart conference remote projection device. Background Art

[0002] During projection at a conference venue, the existing projector is generally placed on a conference table for projection. It is not convenient to adjust the installation height of the device, and it is not convenient to fix the projection height. The projection screen angle needs to be adjusted back and forth, which affects the projection effect. Among them, the "projection device for an intelligent video conferencing interactive system" disclosed in the application number "CN202122371148.4" is also an increasingly mature technology. The slider can be used to slide up and down in the slide groove through the movable arm rod to freely adjust the projection height of the projector body. After the slider is slid to the appropriate position, the arc-shaped elastic locking piece can be used to pop out of the locking hole and adjust the projection height of the projector body. The device can be limited in height by simply pressing down the arc-shaped elastic locking piece and sliding it downward or upward into a suitable locking hole when changing the height. The walking rollers facilitate the handling and transportation of the device. When it is moved to a designated location, the rotating shaft can be rotated to contact and support the bottom surface of the L-shaped friction foot pad on the ground, thereby increasing its static friction coefficient. It is also more stable when supported and will not shake easily during projection. However, the device still has the following defects: when the projector is projecting a picture, the projector is in the process of projection, and the projected picture will shift when it is projected in the designated area. Currently, when adjusting the projection picture, manual adjustment is required when the picture shifts, and the accuracy is poor. Utility Model Content
